BACKGROUND

In daily life, users may sometimes have requirements for recognizing photographed images. In the known technologies, image recognition is to recognize images using a recognition model established by analyzing features of massive images. However, when the images are recognized using the above approach, on one hand, the above approach is not suitable for personal users because larger resources are consumed in the recognition process. On the other hand, because the recognition model may only be adjusted according to a recognition result outputted by a machine, deviation may be caused to adjustment of the recognition model when more errors occur in the outputted recognition result, which may further reduce the recognition accuracy.

The network 104 serves as a medium providing a communication link between the terminal devices 101, 102 and 103 and the server 105. The network 104 may include various types of connections, such as wired or wireless transmission links, or optical fibers.

It should be appreciated that the numbers of the terminal devices, the networks and the servers in the virtual machine cluster in FIG. 1 are merely illustrative. Any number of terminal devices, networks and servers may be provided based on the actual requirements.

Referring to FIG. 2, a flow 200 of a method for recognizing an image according to an embodiment of the present disclosure is illustrated. It is to be noted that the method for recognizing an image provided by the embodiments of the present disclosure generally is performed by the terminal devices 101, 102 and 103. Correspondingly, the apparatus for recognizing an image generally is arranged in the terminal devices 101, 102 and 103. The method comprises following steps.

Step 201: acquiring a to-be-recognized image containing a to-be-recognized object.

In this embodiment, the to-be-recognized image may be captured by a camera. The camera may be arranged on the terminal device. The terminal device may comprise but is not limited to a mobile terminal or a wearable device (for example, smart glasses). Taking the smart glasses being arranged on the camera as an example, when the user wears the smart glasses, the camera may be utilized to capture an image within a viewing angle range of the camera to serve as the to-be-recognized image. In this embodiment, the camera may be started for image capture in response to inputting an image capture instruction. For example, voice information inputted by the user may be received via a microphone, the voice information is resolved to obtain the image capture instruction, and the camera is triggered for image capture. In this embodiment, the to-be-recognized image comprises a to-be-recognized object. For example, when the user enters a conference site, the camera on the wearable device worn by the user may be utilized to capture an image associated with the scene of the conference site, and the captured to-be-recognized image may comprise the to-be-recognized object such as a table or chair in the conference site.

In some optional implementations of this embodiment, the to-be-recognized object comprises at least one of: a body object, a scene object and a color object.

Step 202: sending the to-be-recognized image to the server, and receiving identification information of a target object corresponding to the to-be-recognized object returned by the server, obtained by recognizing the to-be-recognized image, and a confidence parameter returned by the server.

In this embodiment, the confidence parameter represents a probability of the to-be-recognized object being the target object.

After acquiring the to-be-recognized image, the to-be-recognized image may be sent to the server to recognize the to-be-recognized object in the image, and then the confidence parameter and the target object corresponding to the to-be-recognized object, obtained by recognizing the to-be-recognized image by the server may be received. An optional recognition pattern for recognizing the to-be-recognized image by the server is a machine learning recognition pattern. In this embodiment, the confidence parameter may be used for representing a probability of the to-be-recognized object being the target object (namely, the similarity between the to-be-recognized object and sample data of the target object) when recognizing the to-be-recognized image. The higher the value of the confidence parameter is, the larger the probability of the to-be-recognized object being the target object is.

Step 203: determining the identification information of the target object as a recognition result when the confidence parameter is greater than a confidence threshold; or acquiring labeled information associated with the to-be-recognized image from a third-party platform and determining the labeled information as the recognition result when the confidence parameter is smaller than the confidence threshold.

In this embodiment, optional labeled information comprises information containing the identification information of the target object corresponding to the to-be-recognized object, wherein the information is released by a registered user of the third-party platform. In this embodiment, after obtaining the confidence parameter returned by the server, the recognition result of the to-be-recognized image may be further determined. When the confidence parameter is greater than the confidence threshold, the identification information of the target object may be determined as the identification result. When the confidence parameter is smaller than the confidence threshold, the labeled information associated with the to-be-recognized image may be acquired from the third-party platform. Taking the to-be-recognized image including one round table and three chairs as an example, when the to-be-recognized image is recognized by means of the server in a machine recognition pattern, for example, when the to-be-recognized object is matched with the target object (namely, sample data of the round table object and the chair object), in the event that the confidence parameter is greater than the confidence threshold, identification information (namely, the table and the chairs) of the target objects (namely, table object and chair object) may be determined as the recognition result. In the event that the confidence parameter is smaller than the confidence threshold, the to-be-recognized image may be sent to the server, labeled information returned by the server may be received, and the labeled information may be determined as the recognition result.

In this embodiment, the labeled information of the to-be-recognized object may be acquired in the following ways: the to-be-recognized image may be sent to the third-party platform associated with the server, the third-party platform may provide question answering services, wherein the question answering services may be used for issuing questions asked by the user in the form of task, and the answers of the questions are published on the third-party platform by a registered user of the third-party platform. After the to-be-recognized image is sent to the third-party platform, a task for recognizing the to-be-recognized image may be generated using the question answering services of the third-party platform, and then the task is issued to the registered user of the third-party platform. When the registered user receives the task for recognizing the to-be-recognized image, an information input region may be provided when the to-be-recognized image is shown to the registered user. The registered user may determine which target objects are included in the to-be-recognized image, and then fill information such as names and number of the target objects into the information input region. In this way, the labeled information is generated. For example, when the to-be-recognized image in the task for recognizing the to-be-recognized image received by the registered user comprises one round table and three chairs, the registered user may fill information into the information input region using the following formats: round, table, one, chairs, and three. Next, the labeled information may be generated based on the information filled by the registered user. The labeled information includes identification information of the target object corresponding to the to-be-recognized object (namely, “round table and chairs”), and may further include information representing the number of the target objects (namely, “one and three”).

In some optional implementations of this embodiment, the method further comprises: converting the recognition result into voice information and playing the voice information. In this implementation, after obtaining the final recognition result, the recognition result may be converted into voice information, and then the voice information is played for the user.

In some optional implementations of this embodiment, the method further comprises: sending the labeled information to the server to serve as a training sample for training a recognition model corresponding to a machine learning recognition pattern used by the server when the confidence parameter is smaller than the confidence threshold.

The application scene of this embodiment may be as below: a user (for example, a blind user) uses a camera on a wearable device to capture a to-be-recognized image (for example, a to-be-recognized image including to-be-recognized objects such as tables and chairs in a conference site) associated with the current scene (for example, the conference site). Next, the to-be-recognized image may be sent to the server to recognize the to-be-recognized image, and identification information of a target object corresponding to the to-be-recognized object and a confidence parameter which are returned by the server are received. When the confidence parameter is greater than a confidence threshold (for example, table and chair objects are accurately recognized), the identification information of the target object corresponding to the to-be-recognized object may be determined as the recognition result. When the confidence parameter is smaller than the confidence threshold, the to-be-recognized image may be sent to the third-party platform, so that the registered user of the third-party platform determines the target object (for example, the registered user determines that the to-be-recognized image includes target objects such as tables and chairs) corresponding to the to-be-recognized object, then labeled information, containing the identification information of the target object corresponding to the to-be-recognized object, returned by the third-party platform may be received, and the labeled information is determined as the recognition result. After determining the recognition result, the recognition result may be converted into voice information for playing. In this way, the user may relatively accurately learn situations of the current scene (for example, which objects are included in the scene) based on the captured image. Further, when the confidence parameter is smaller than the confidence threshold, labeled data may be sent to the server to serve as a training sample for training a recognition model corresponding to a machine learning recognition pattern used by the server to enhance a training effect of the recognition model, so that the recognition accuracy may be further enhanced in subsequent image recognition.

Referring to FIG. 3, a flow 300 of a method for recognizing an image according to an embodiment of the present disclosure is illustrated. It is to be noted that the method for recognizing an image provided by the embodiments of the present disclosure generally is performed by a server 105. Correspondingly, the apparatus for recognizing an image generally is arranged in the server 105. The method comprises following steps.

Step 301: receiving a to-be-recognized image containing a to-be-recognized object sent by a client.

In this embodiment, the to-be-recognized image comprises a to-be-recognized object. For example, when the user enters a conference site, the camera on the smart glasses may be utilized to capture an image, and the captured image may comprise the to-be-recognized object such as a table or chair.

Step 302: recognizing the to-be-recognized image to obtain identification information of a target object corresponding to the to-be-recognized object and a confidence parameter.

In this embodiment, the confidence parameter represents a probability of the to-be-recognized object being the target object. An optional implementation for recognizing the to-be-recognized object is a machine learning pattern. The machine learning pattern may include but is not limited to an auto encoder, sparse coding and deep belief networks. The machine learning pattern also may be referred to as deep learning.

In some optional implementations of this embodiment, recognizing the to-be-recognized image comprises: recognizing the to-be-recognized image using a convolutional neural network model.

In this embodiment, a recognition model corresponding to the machine learning recognition pattern used by the to-be-recognized image may be first established, and then the to-be-recognized image is recognized by using the recognition model. The principle of recognizing the to-be-recognized image using a recognition model corresponding to the machine learning pattern is outlined as below: when the to-be-recognized image is recognized using the recognition model (for example, the convolutional neural network model), the to-be-recognized object in the to-be-recognized image may be indicated by some features (for example, scale invariant feature transform feature points) to generate an input vector. After the to-be-recognized image is recognized using the recognition model, an output vector representing a target object corresponding to the to-be-recognized object may be obtained, the recognition model may be used for indicating a mapping relation from the input vector to the output vector, and then the to-be-recognized image may be recognized based on the mapping relation.

In this embodiment, when the to-be-recognized image is recognized using the recognition model, the to-be-recognized object in the to-be-recognized image may be represented by some features (for example, scale invariant feature transform feature points), features of the to-be-recognized object (for example, table object) in the to-be-recognized image may be matched with the target object (for example, sample data of the table object) to obtain the confidence parameter representing a probability of the to-be-recognized object being the target object.

In some optional implementations of this embodiment, the method further comprises: receiving a recognition result for training sent by the client, wherein the recognition result for training comprises labeled information associated with the to-be-recognized image and acquired from a third-party platform, and the labeled information comprises information containing the identification information of the target object corresponding to the to-be-recognized object, the information being released by a registered user of the third-party platform; and training, by using the recognition result for training, a recognition model corresponding to a machine learning pattern.

In this embodiment, the recognition result for training sent by the client may be labeled information associated with the to-be-recognized image acquired by the client from a third-party platform when the confidence parameter obtained by recognizing the to-be-recognized image using the machine learning pattern is smaller than the confidence threshold. The labeled information comprises information containing the identification information of the target object corresponding to the to-be-recognized object, wherein the information is released by a registered user of the third-party platform. Taking the to-be-recognized image including a round table and three chairs as an example, when the confidence parameter obtained by recognizing the to-be-recognized image using the machine learning pattern is smaller than the confidence threshold, that is, when round table or chair objects are not recognized accurately, the client may be triggered to send the to-be-recognized image to the third-party platform (for example, the third-party platform providing question answering services) to obtain labeled information of the image. The labeled information may be information containing the identification information of the target object corresponding to the to-be-recognized object, wherein the information is released by the registered user of the third-party platform. For example, the labeled information comprises “round table, one, chairs, and three”.

In this embodiment, the recognition model may be trained using the labeled information. Taking the recognition model being a convolutional neural network as an example, a feature (for example, a scale invariant feature transform feature point) of the to-be-recognized image may serve as an input vector of the convolutional neural network, the labeled information may serve as an ideal output vector of the convolutional neural network, and the convolutional neural network may be trained by constituting a vector pair by the input vector and the output vector, so that the recognition model may be trained using a correct recognition result (namely, labeled information acquired by recognizing the to-be-recognized image by the registered user of the third-party platform artificially). In this way, the training effect of the recognition model is enhanced, and further the recognition accuracy is enhanced in the subsequent recognition of the to-be-recognized image.

In this embodiment, sample data corresponding to a type of the to-be-recognized object may be preset according to the type of the to-be-recognized object, and then the recognition model is trained using the sample data. For example, images of some common application scenes and labeled information of the images may be acquired in advance to serve as training data.

Step 303: sending the identification information of the target object and the confidence parameter to the client.

In this embodiment, after recognizing the to-be-recognized image, the identification information of the target object corresponding to the to-be-recognized object in the to-be-recognized image and the obtained confidence parameter may be sent to the client.

The determining unit 403 is configured to determine the identification information of the target object as a recognition result when the confidence parameter is greater than a confidence threshold, or acquire labeled information associated with the to-be-recognized image from a third-party platform and determine the labeled information as the recognition result when the confidence parameter is smaller than the confidence threshold.
